Abstract

PURPOSE: To realize a good labyrinth seal with a simple structure by providing a seal element having a flange extending in the radial direction and a portion extending in the axial direction in a space between a shaft or the like and an intermediate bushing.
CONSTITUTION: In a space between a shaft 2 and an intermediate bushing 11 at both ends in the axial direction, a seal element 17 which almost fills this space is arranged. This seal element 17 is made of a bushing with the cross section in the shape of 'L', and a flange 18 extending outside in the radial direction enters an annular recess 15 of the intermediate bushing 11. By a labyrinth seal gap 19 caused by this, a good seal can be obtained for a bearing. The seal element 17 is arranged on the shaft 2 with a contact pressure in the radial direction at the portion extending in its axial direction and rotated together. Thus, a centrifugal disc effect for preventing intrusion of stain and water is generated by the flange 18 of the rotating seal element 17.
